Claims. (Cl. 134-172 This invention is directed to improvements indish-' washing machines and is particularly directed to a water pressuredishwasher having a collapsible hood arrangement particularly adapted todoing large volumes of dishes but Which may be folded up and easilyputaside in a cabinet or drawer when not in use.

One of the primary objects of this invention is to provide an improveddishwashing machine having a collapsible top which may be readily swungup and over the dishes to be washed while at the same time providingadequate spray for the dishes both above and below the receptaclecontaining the dishes.

Still another object of this invention is to provide a full capacitydishwasher which may be folded up and put away with a minimum of spaceutilization.

Still another object of this invention is to provide an improveddishwashing machine with a novel top arrangement which may readily beswung up into operative position or withdrawn and folded downwardly foreasy access to all the dishes in the apparatus.

Still another object of this invention is to provide an improved waterpressure dishwasher particularly adapted for use on the sink top inconjunction with the regular sink in the kitchen and the like.

Further features and advantages of this invention will appear from adetailed description of the drawings in which:

Fig. 1 is a side elevation of a dishwashing machine incorporating thefeatures of this invention.

Fig. 2 is an end elevation of the apparatus shown in Fig. 1.

Fig. 3 is a section on the line 33 of Fig. 2.

Fig. 4 is a section on the line 4-4 of Fig. 1.

Fig. 5 is a side elevation similar to that of Fig. 1 but showing the topin retracted position.

As an example of one embodiment of this invention there is shown a waterpressure dishwasher having a main base pan having a bottom 11 and theintegral sides 12 and 13 and the ends 14 and 15. Suitable raised supportbrackets 16 fixed to the inside faces of the ends 14 and carry thedish-holding basket 17 in which are placed the dishes to be washed.

The top edges of the sides and ends is formed by an upturned flange 18forming a ledge 19 around the upper portion of the base pan 19. Acollapsible cover is formed of a series of ribs 20, 21 and 22 pivotallymounted to swing around an axis 23 on the upturned flange 18 at thesides 12 and 13 of the base pan 10. Suitable plastic cover material isconnected to the outside of the ribs at 24, 25, 26 and 27. The plasticmaterial portion 24 is secured water-tight along its lower edge to theledge 19 between the axis of rocking 23 and the end 14 of the base pan10. The other portion is connected to the swinging hoop or rib 28 havingthe manipulating handle 29. The entire assembly of the ribs 20, 21, and22 and the plastic 24, 25 and 26 and 27 may be swung up over the dishesin the basket 17 as shown in Fig. 1 or swung back down in retractedposition as shown in Fig. 5 for removal of the 2,771,895 Patented Nov.27, 1956 dishes and for storage of the iinit walla of vertlply conduitis formedat 30 and-31 integral with the rib' 21 and in fact maypreferably form said rib. It connects with a hinged fluid connection 32with the pressure water supply pipe 33 which is preferably connected "tothe hot water tap at the sink. 'There is also a fixed discharge line 34from the hinge fluid connection 32 extending to the horizontal supplyline 35 which terminates at the mid point of the bottom 11 of the basepan 10 to supply the lower spray element 36 located under the dish basket 17.

Thus, with the dishes loaded in th'e baske' t 17' the hood may beswung'u'p'by manipulationof the handle 29 from the'position shown inFig. 5 to 'the position shown in Fig. 1 which automatically brings" thewater sp a element 29iz'up centrally over'the dishes. Water pressure isthen turned on in the line 33 and both of the spray elements 29a and 36go to work rapidly to rinse ofl the dishes. A suitable drain spout maybe provided at 37 in the bottom of the pan 10 which discharges into thesink for removal of the excess water and foreign matter from the dishesas they are washed ofl by the spray elements 29a and 36. At thecompletion of the dishwashing operation the water is turned off and thecover swung down to the position indicated in Fig. 5 for easy access tothe dishes. Furthermore, it may be folded down completely to the top ofthe upturned flange 18 and the dish basket 17 placed back in the regularsink or otherwise disposed of so that the entire dishwashing unit maynow be easily slipped into a drawer or cupboard with a very minimum ofheight from the bottom 11 to the top of the upturned flange 18 of theunit.

Thus there has been provided a highly efficient table top dishwashingmachine which is collapsible for easy storage and access to the dishes.

While the apparatus herein disclosed and described constitutes apreferred form of the invention, it is also to be understood that theapparatus is capable of mechanical alteration without departing from thespirit of the invention and that such mechanical arrangement andcommercial adaptation as fall within the scope of the appended claimsare intended to be included herein.

Having thus fully set forth and described this invention what is claimedand desired to be obtained by United States Letters Patent is:

1. A dishwashing machine including a readily portable base pan, acollapsible top mounted on the top edge of said pan having a series ofribs pivotally mounted to swing about a horizontal axis located midwaythe sides of said pan, a flexible waterproof cover mounted over theoutside of said ribs having one end thereof secured to the top edge ofsaid pan between one end of said pan and said pivotal axis, and a waterspray element mounted on the inside of one of said ribs.

2. A dishwashing machine including a readily portable base pan, acollapsible top mounted on the top edge of said pan having a series ofribs pivotally mounted to swing about a horizontal axis located midwaythe sides of said pan, a flexible waterproof cover mounted over theoutside of said ribs having one end thereof secured to the top edge ofsaid pan between one end of said pan and said pivotal axis, a waterspray element mounted on the inside of one of said ribs, said ribcarrying said water spray element including an integral water supplyconduit, and a hinge fluid connection on said pivotal axis connected tosaid conduit.

3. A dishwashing machine including a readily portable base pan, acollapsible top mounted on the top edge of said pan having a series ofribs pivotally mounted to swing about a horizontal axis located midwaythe sides of said pan, a flexible waterproof cover mounted over theoutside of said ribs having one end thereof secured to the top hingefluid connection on said pivotal axis connected to said conduit, a rigidconduit in said pan in communication with said hinge fluid connection, adish basket carried in said pan adapted to be covered by saidcollapsible top, and a lower water spray element in said pan below saidbasket.
